APAR status
Closed as program error.
Error description
By default ACE enables TLSv1 and TLSv1.1 even if it is part of jdk.tls.disabledAlgorithms in the java.security file. This allows SOAPRequest/HTTPRequest node to complete an SSL handshake by using TLSv1,TLSv1.1,TLSv1.2 or TLSv1.3 if the node is configured with TLS as the protocol. In some scenarios it may required to prevent the SSL handshake using TLSv1 and TLSV1.1 algorithms that are part of jdk.tls.disabledAlgorithms property.
